Display device

A display device, comprising:

• a pixel array substrate, having a display surface and a bottom surface opposite to the display surface, wherein the display surface has a plurality of pixel regions and a plurality of light transmitting regions, and the pixel regions are arranged alternately with the light transmitting regions in a first direction;
• a plurality of light emitting elements, disposed on the display surface and electrically connected to the pixel array substrate, wherein the light emitting elements are located in the pixel regions;
• a lower plate, wherein the bottom surface is located between the display surface and the lower plate;
• a black pattern layer, disposed between the pixel array substrate and the lower plate in a second direction perpendicular to the first direction, and having a plurality of light shielding parts and a plurality of first opening areas, wherein the light shielding parts are arranged alternately with the first opening areas in the first direction;
• a cover plate, disposed on the light emitting elements;
• and
• a transparent medium pattern layer, disposed between the cover plate and the light emitting elements, wherein the transparent medium pattern layer has a plurality of medium parts and a plurality of second opening areas, the medium parts are arranged alternately with the second opening areas in a third direction perpendicular to the second direction, and third direction is different from the first direction.
